My 2002 Subaru outback has about 191000 miles on it and recently it has started to idle around 250-300 rpms. my boss told me to clean some kind of idler but idk where to find it or how to clean it. does anyone know?
Also my subaru keeps having the code P0240 - Catalyst System Efficiency below threshold (Bank 1), but we replaced the O2 sensor and the cat and the light keeps coming back on. Any suggestions on it?
Thanks!
